IEC SAFETY LIMITING VALUES
Safety limiting intends to prevent potential damage to the isolation barrier upon failure of input or output (I/O) circuitry. A
failure of the I/O circuitry can allow low resistance to ground or the supply and, without current limiting, dissipate sufficient
power to overheat the die and damage the isolation barrier, potentially leading to secondary system failures.
The safety-limiting constraint is the operating virtual junction temperature range specified in the Absolute Maximum Ratings
table. The power dissipation and junction-to-air thermal impedance of the device installed in the application hardware
determine the junction temperature. The assumed junction-to-air thermal resistance in the Thermal Information table is that of
a device installed in the JESD51-3, Low Effective Thermal Conductivity Test Board for Leaded Surface Mount Packages and
is conservative. The power is the recommended maximum input voltage times the current. The junction temperature is then
the ambient temperature plus the power times the junction-to-air thermal resistance.
